Narrated by Abu Huraira (may Allah be pleased with him): The Messenger of Allah (peace and blessings be upon him) went to the toilet, so I brought a vessel of water to him. He performed istinja (cleaning) with it, then rubbed both his hands on the ground and then washed them. Then I brought another vessel, and he performed ablution (wudu) with it.
